【摘要】：目的检验反复体位改变训练在提高人体对血液重新分布适应性方面的有效性 ,寻找可行的训练方法。方法 1 2名被试者随机分为A、B两组 ,每组 6人 ,分别接受 1 1d共 9次的A模式和B模式 (头低位、头高位快速交替 )的反复体位改变训练。训练前、后进行头低位 (HDT - 30°/30min)耐力检查和立位耐力检查 ,以评价训练效果。结果 1 ) 2种模式的反复体位改变训练均提高了被试者的HDT耐力 ;与训练前相比 ,训练后在HDT耐力检查中 ,B组的症状得分明显小于A组 (P 0 .0 5 ) ,B组心率降幅明显增加 (P 0 .0 1 ) ,说明B模式的训练在提高HDT耐力方面的效果较好 ;2 )两种模式的反复体位改变训练均使被试者的立位耐力有一定程度的改善 ;与训练前相比 ,训练后在立位耐力检查中 ,B组平均动脉压增幅明显增加 (P 0 .0 5 ) ,心率的增幅呈现小于A组的趋势 (P 0 .1 0 ) ,说明B模式的训练在提高立位耐力方面的效果略好。结论反复体位改变训练可提高人体对血液重新分布的适应性 ;B模式是相对较好的训练方法 ,有望在航天员血液重新分布适应训练中得到应用。
[Abstract]:Objective to test the effectiveness of repeated posture change training in improving the adaptability of human body to blood redistribution, and to find a feasible training method. Methods Twelve subjects were randomly divided into two groups: group A (n = 6) and group B (n = 6). They were trained for 11 days and 9 times in mode A and mode B respectively. Before and after training, head-low (HDT-30 掳/ 30 min) endurance tests and orthostatic endurance tests were performed to evaluate the training effect. Results 1) repeated postural changes in both models improved the HDT endurance of the subjects compared with those before training. After training, the score of symptoms in group B was significantly lower than that in group A (P0. 05), and the decrease of heart rate in group B was significantly higher than that in group B (P0. 01). It shows that the training of mode B has a better effect on improving HDT stamina. 2) the repeated changes in posture of both modes can improve the standing endurance of the subjects to some extent, compared with those before training. After training, the mean arterial pressure increased significantly in group B (P0. 05), and the increase of heart rate was smaller than that in group A (P 0. 100), which indicated that the training of mode B had a slightly better effect in improving standing endurance. Conclusion repeated posture change training can improve the adaptability of human body to blood redistribution. It is a relatively good training method, and it is expected to be applied in the blood redistribution adaptation training of astronauts.
